Application filed August 28, 1906. Serial No. 276,128.

To all whom it may concern:

Be it known that I, MICHAEL J OHN HANEY,

. civil engineer, of the cit of Toronto, in the count of York, in the rovince of Ontario, Cana a, have invented certain new and useful Improvements in Double- Interlocking Concrete Slab-Cribs, of which the following is a specification.

y invention relates to improvements in double-interlockingmoncrete slab-cribs; and

the object of the invention is to devise a uickly-assembled, inexpensive, strong, and

urable form of cribwork in which the. coricrete portions forming parts thereof may be simply and securely adjusted; and it consists, essentially, of face=slabs with suitable projecting portions at the ends thereof, crosstie slabs with'sup lementary projecting ortions extending 'tlierefrom and desi e to receive the extending portions from t e faceslabs, and cross-ties extending from face-slab, to face-slab, suitably and movably attached thereto, and designed .to take tensile strain, all arranged and constructed as hereinafter more particularly explained.

Figure 1 is a plerspective view of my cribwork, showing t e continuous method of interlockin adjoinin slabs. Fig. 2 is an enlarged si e view 0 my double-interlocking 'oint, showing the method of securing the iace-slabs and cross-ties together. Fig. 3 is an enlarged perspective view of m doubleinterlocklng joint with one of the ace-slabs removed. Fig. 4 is a plan detail of the nlielthod of fastening the cross-ties to the faces a In the drawings like letters of reference indioate correspondin parts in each figure.

A A are the two ace-slabs of a single crib with substantial projecting ortions A extending from the ends thereo the upper face of said portions being fiat and the lower of a V-shaped cross-section sloping inwardly from the outer to the inner face of said slabs,

as shown clearly in Fig. 3.

B B are the end cross-tie slabs of the cribbing with substantial projecting portions B extending therefrom, having a V-shaped groove upon the up or face thereof, the contour of said groove eing designed to fit the V-shaped face of the extending portions A as shown in Figs. 2 and- 3.

C Care reinforced concrete cross-ties having angle-irons D and D extending therein, symmetrically designed and placed, the flanged portionsD or arms of said angles sax-- tendin away from each other and slightly beyon the end of said cross-tie, as shown in Fig. 4. A tubing or the like D is provided between the angle-irons, through which a bolt D extends and holds the aforesaid irons relatively rigid when the concrete is green.

E E are channel bars symmetricall placed, extendin into and running the widt of the face-slab, aving the flan ed portions E E extending toward each ot er and beyond' the face-slab, forming, with the faceslab, a channel or groove in which the flanged portions D are designed to be securely and movably held, as shown in Figs. 1 and 4.

F is a lattice-work bolted to the flanges F of the channel-bars and designed to hold them in place when the concrete. is green. I-I re resents the face-slabs of the adjoining cri which are rovided with portions H, extending from t e ends thereof and of a form identical with that of the projections from the aforesaid face-slabs.

l? I are suitable piles upon which the said cribwork rests.

The V-shaped grooves and the su plementary portions extending therein are aced with a suitable plating R, bolted or otherwise secured to the concrete backing of the slabs, as shown in Figs. 2 and 3.

In forming a continuous cribbing the crosstie slabs B are placed upright on suitable pile foundation having the V-shaped faces of the projecting portions facing upwardly. The ace-slabs A A are then lowered, and when the V-sha ed face of the extending portion becomes a jaoentto the projecting portion of the cross-tie slabs the face-slabs are given a lateral motion and, coming in contact with the cro'sstie slabs, slide into position, as most clearly shown in Fig. 3. Theface-slabs H of thee joining crib are laced in position in an identical manner on t e cross-tie slabs, v

forming when in position a doubly-interlockingjoint. The interlocking ortions follow consecutively, the portions om the crosstie slabs extendin between the extending ortions from the ace-slabs. When no adoinin forme b doubling the number of extending V-forme rojecting portions on the faceslab, thus ing the position theretofore occupied by the exempted extending portions of the adjoining face-slab, as shown in Fig. 1, and stren themng the joint at the same time. It will be noticed that no other clamping or fastening means is required when once the cribs are to be added, the joint is plates or face-slabs are in place, since their tendency is to slide alwa s inwardly and downwardly and according y, owi n totheir extreme heaviness, are not easily There is a clearance-space allowed between the rojecting ortions of the cross-tieslabs to a low for su cient downward inclination of the V-shaped faces of the face-slabs. This clearance-space is afterward filled with com- 10 position. I

It will be seen that with such an invention as I have described a complete, cheap, and substantial cribbing is provided and should proge itself capable of'withstanding the ex- I 5 posiure and usage for which it is devised.
